I stopped using Alacritty because of these memory leaks. I think that this is not BSPWM problem at all.

Try reproducing this with a minimal amount of external factors: for example when picom & polybar are not running.

Which processes are actually using more memory?

Also, i’ve tried to measure memory usage by htop, but it is very strange that it doesnt show all of memory consumers. For examle, when I was fixing my picom (by the way it was about memory consumption too) I tried to analyze memory usage in htop too, but it was showing that everything was ok. The problem was in the fact that picom was rerendering window again and again, so my memory said goodbye. It makes me mad sometimes when htop hides some essential information from me
